Answer 2

The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Calculating scientific notation for a positive integer is simple, as it always follows this notation:

a x 10b

Follow the steps below to see how 3,643 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 3,643

New Number: 3.643

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 3 . 6 4 3

Decimal Count: 1 2 3

There are 3 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 3.643

b = 3

Now the whole thing:

3.643 x 103

Step 4

Check your work:

103 = 1,000 x 3.643 = 3,643
